To all 'whom it may concern Be it known that I, HARVEY H. Wnnmnn,

a citizen of the United States, residing at Plymouth, in the county of Marshall and State of Indiana, have invented certain new and useful Improvements in Photogra h- Printing Stands; and I do declare the ollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to phot and more especially to the printmg o hotographs from the negative plates; and t e object of the same is to produce a stand haying a hollow body containing the electrlc lights and having a hole in its top, and an improved construction of carriage movable over said top and either across the hole or away from over it, and held in firm contact with the sensitive paper which overlies the negative.

This and other objects are carried out by constructing the device in the manner here. inafter more fully described, and as shown in the drawings wherein- Figure 1 is a side elevation of this, stand complete, showing the carriage at about the mid-length of its movement in full lines, and showing the top of the stand in dotted lines as tipped to the rear; and Fig. 2 is a front elevation, while Fig..3 is a planview thereof. Fig. 4 is an enlarged longitudinal section with the carriage in its foremost or forward position, and Fig. 5 a similar section with the carriage retracted to its rearmost position. Figs. 6, 7 and 8 are cross sections on the lines 6 -6, 7-7, and 8-'8 respectively of Fig. 4. Fig. 9 is a longitudinal section of one of the guide fingers hereinafter referred to.

In the drawings is shown a stand, herein illustrated as comprising legs 1 carrying a hollow body 2 within which is disposed a ruby or orange light 3 and a white light 4, the same in the present instance being illustrated as incandescent lights in circuit with a switch 5 whose switch arm 6 projects through the top 7 of the stand as bestindicated in Fig. 4. As usual in devices of this character, especially where they are employed for rapid commercial photograph printing, the electric circuit indicated in diagram in this view is connected up with Vlower end of said a source of plower so that when the switch is thrown to t e position shown in Fig. 4 the white light 4 is turned on and rinting occurs, but when the parts standp as seen in Fig. 5 the switch is at the other extreme and the red or orange light 3 is burnin so that the sensitive paper 1s `not fogged. he top 7 of the stand is preferably hinged at 8 in rear of its body-2, and across the front of said top on its under side is a cleat 9 carrying a hook 10 with which is engaged a spring catch 11 attached to or connected with the body in any suitable manner, so that when it engages the same the top is held horizonta-l as seen in full lines in Fig. 1, but when it is retracted to disengage the hook 10 the top may be turned over as seen in dotted lines in that view and access to the hollow body may be had as for repairing or cleaning the lights. By preference I attach the catch 11 to a narrow door 12 extendin across the front of the body and hinge thereto as at 13, and when the catch is disengaged from the hook this door also may be turned downto give greater freedom 'of and access to the interior.

So much of my device as has alread been described may be constructed of woo with suitable hardware, and the whole properly finished and of suitable dimensions.

In the top 7 is an opening designated at 14 in Fig. 6, and the edges of said opening are rabbeted as at 15; and within said rabbet may be placed the glass plate or negative if it is of a size to fit the same, or a reducing frame 16 if the plate 17 is smaller than 'the opening-the frame itself being rabbeted around its inner edge yas the upper face of the plate '17 shall stand flush with the upper face of the table 7 and the upper face of the reducing frame 16 if the latter be employed.

Pivoted to ystandards 20 risingfrom the table top 7 near its rear endare guide rods 21 whose front ends are turned downward through tubes 22 which are rigidly secured in the table top near its front end, and the downturned portions 23 carry nuts or sto s 24 between which and the lower ends osaid tubes are spiral expansive springs 25 whose force is exerted in drawing said downturned portions 23 and the front endsof the rods 21 downward so that normally the latter do not stand quite seen at 18 so that parallel with the table topsee Fig. 5. I would give the springs 25 some considerable tension for a purpose yet to appear, and l would dispose the guides 21 near the side edges of the table top 7 so that ample space is left between'them. llVithin this space is located a carriage, comprising a closed top having a handle 31 rising from it, upright sidcs`32 in which are journaled the pintles 33 of a series of idle rollers 34 standing close to but out of contact with each other and all of equal size, and in which sides 32 are also journaled the pintles 35 and 3G of a spring roller 37, the same being mounted a little higher than the other rollers as best seen in Fig. l. One pintle 36 of this spring roller is angular, and is normally engaged by a catch 38 pivoted at 39 to the contiguous side 32 of the carriage, so that when this catch is raised the angular pintle can be given additional rotation to increase the tension of the spring within the roller 37, after which the latch will be again dropped into place as shown in Fig. 1. Connected with the spring roller is a belt, here shown as consisting of cords or strings lO,

and connected with the forward end of this belt is a mat 41 which is by preference composed of a rat-her thick but extremely flexible sheet of rubber, the same extending over the top of the various idle rollers, around the front one, and to the rear over the table top to which it is secured as at 4t2; and as seen in Fig. 8 this mat is of greater width than the opening in the table top, or in the reducing traine il one be employed.

Projecting laterally from the carriage are stub shafts 50 on which are journaled grooved rollers 51 traveling beneath the guide rods 2l, and it will be clear that the expansive force of the springs 25 which depresses the front ends of said rods, also causes the depression of said grooved rollers 51 and results in bearing the entire carriage down toward the table top and pressing its various rollers onto the mat and the latter onto the paper and negative. Therefore when the carriage is drawn forward so that the bend in the mat grips even a corner or an edge of the sensitive paper, the lat-ter is pressed into close contact with the negative plate 17 and movement between these parts is prevented. The result is that prints made from this machine show no blur which is such a common fault.

Each stub shaft carries a guide linger, best illustrated in Fig. 9. This consists of a shank 52 standing alongside the carriage and having an eye 53 atits rear end loosely mounted on said stub shaft inside its Wheel 51, the other end of the shank being upturned as at 54e and carrying a hook 55 whose bill 56 loosely embraces the guide rod 21 and whose inner end is slotted as at 57 and loosely engages a headed pin 58 on the front end of the carriage. The result ot' this detail of construction is that said carriage at its `lront end is accurately guided laterally, or in other words held at its proper position between the two longitudinal guide rods 21, while at thc saine time it is permitted to move over the face of the table top 7 and the plate 17 whether the guide rods 2l are drawn well down through the tubes 22 as seen in Fig. 5, or not, and leal.z springs GO press the hooks down onto said rods as best seen in Fig. 6. One of the upturnerl portions 54 at the front end of a linger, as on the right side ot the carriage, may well be used as a cam or projection which strikesI the upper end of the switch arm 6 as indicated in Fig. 4, and ir" so a spring will retract the arm as indicated in Fig. 5.

T-With the above construction of parts, the operation of this printing stand is as foll lows: lVith one hand the operator lays the sensitive paper over the plate 17 and with the other hand he'grasps the handle 31 and draws the carriage forward to the position seen in Fig. 4. As it reaches the forward limit of its movement, the switch arm 6 is thrown so that the white light or lights 4 is or are cut into circuit, and printing commences within the hollow body 2. The operator may now release his grip on the handle 31, as the tension of the springs 25 is suiiicient to hold the carriage at any point along its course-despite the tension. of the spring within the roller 37. Having given the exposure a suiiicient length of time, the operator has but to grasp the handle 31 and move the carriage back-either to its extreme rearmost position as seen in Fig. 5 if the negative and the print be of considerable size, or only part way back as seen in Fig. 3 if he be printing a small picture which will of course overlie the front edge only oi the plate 17. The use of a reducing 'frame for holding small-sized glass negatives is too 11o well known to need repetition here. Attention is directed to the fact that the upturned end 54 of one of the guide lingers is so disposed that it throws the switch as the carriage is moved to the eXtreme of its forward 115 travel, and releases the switch as soon as the carriage begins its rearward travel thus turning oil1 the white light and turning on the ruby 0r orange light quickly. The operator then removes the print and passes it 120 to the fixing bath, and replaces it with another sheet of sensitive paper so that the operation may be repeated. When now it is desired to gain access to the interior of the hollow body 2, he retracts the catch 11 so 125 as to disengage the hook 10, and immediately the entire top 7 may tilt to the position shown in dotted lines in Fig. l, giving him liberal space in which to reach into said top to clean or repair the bulbs.
